Monitor audio levels on iPhone

Use the Health app to monitor audio levels from headphones and sound levels from your environment. It can be helpful to understand how long and often you’re exposed to loud volume as it can affect your hearing.

View audio levels

After you connect EarPods, AirPods, and other compatible headphones to your iPhone, the audio levels are automatically sent to Health.

After you pair Apple Watch with your iPhone, and set up the Noise app on Apple Watch (watchOS 6 required), environmental sound levels are automatically sent from Apple Watch to Health. See the Apple Watch User Guide.

Note: Measurements are more accurate from AirPods than from headphones connected by wire. Measurements for wired headphones are estimated based on the volume of your iPhone.
